The WS22 was also manufactured here , although based on the British set , it was a totally new revised set specifically designed to cope with jungle -damp conditions.
The set utilized the then new PVC coated wires , special wax was used to seal the fragile RF coils . I have a recorded talk given by a chap who was in the army wireless research depot in Burwood, Melbourne. He said they immersed the set in a tank of water , blew the water off with compressed air , and turned it on, it worked ! The 122 set , the same set but with provision for XTAl control of the TX ... a very nice set to use . I had many QSO's with a 122 set on CW and AM .... one memorable evening I had three CW contacts into USA on the 40mx band .
Having owned the British set ... can I politely write , it's a piece of junk compared to the Aust. set . On standby rx, the Aust. set only requires a very small power , in terms of watts
